To all whom t may concer/n:

Be it known that n Jnnms Lapierre Lassen, a citizen of the Kingdom of Denmark, residing at No. 5 Aa Boulevard, Frederiksberg, near Copenhagen, in the Kingdom of Denmark, have invented certain new and useful lmprovements in Machines for Making and Applying Caps on Bottles and the like, of which the following is a speciication.

The well known bottle caps consisting of a metal disk with an inner lining or packing disk (washer) of cork, pa'steboard, or the like, have hitherto been mad or stamping out the-metal disk simultaneously with the washer by means 0f a die, so that the two cut or stamped parts have the to a bottle a cap produced will have its washer between the metal disk and the neck of the bottle, thereby to a certain degree impeding a tight Y and reliablefconnection between the cap and the bottle. ln order to avoid this diculty, the two disks have been made separately, in some cases, the washer being 'ven a smaller diameter, corresponding to that of the bottle mouth. This latter method makes it necessary to place the packing disk or washer in the metal disk by means of a special operation, which takes time and entails extra expense.

The present invention has for to obviate the disadvantages connected wlth the methods referred to above. According to my invention the bottle cap is made and applied in a continuous series o steps forming virtually a single operation, viz: First the metal disk and thereafter the washer is being given a cut out b a die, the washer the metal or capsule smaller diameter than disk and bein placed centrally on the latter, after which t e edge of the capsule disk is bent over and finally the finished bottle cap is automatically carried to one or more mechanisms which are actuated by the die-mechanism and apply the cap securely on the mouth and around the neck of the bottle.

In order to more fully explain my said invention the same will be described in detail with reference to the drawing, which, by way of example, shows an embodiment of a machine for performing the process in question. The machine is represented in a-side view showing the cutting-die mechanism e by cutting its obj ect and the cap-applying mechanism, in section. i

lin a Vcasing 1 secured to the machine frame, which casing is closed at the top by a screwed-on cylindrical head or cap 2, a piston 3 is movable up and down. rThe piston 3 is connected at the top with the tubular cutting-piston 4 proper, the opening o which is flush with the bore 5 inthe piston, and in this cylindrical channel there is disposed a rod or stop 8, which is held stationary in the casing 1 by means of a pin 9. To enable the piston to move lengthwise, it is made with a slot 10 through which said pin 9 extends. rlhe stop 8 has at the top an oblique surface 11 in registry with the lower limit-surface of an oblique chute 12 in the wall of the casing 1.

ln the top of the casing 1 and in the cylindrical head 2, there are two diametrically opposite, horizontal. slits or openings 13 through which the strip of metal from which the capsule disks are cut is passed in the well-known manner, and above these openings there is disposed a cutting-ring 15 held in place by a ring-shaped nut 14.

ln the cylindrical head 2 a tubular piston 16 actuated by a spring 17 is movable up and down around a rod or mandrel 18 adjustably screwed into the said head, the lower end of said mandrel forming a punch for cutting out the packing disk or washer. In the lower end of the piston 16 a cuttin -ring 20 is held fast by means of a ring-s aped nut 19, said cuttin -ring having an inner diameter corresponing to the outer edge of the bottle mouth, and above this cuttingring the piston is a bore 21 partially furnished with of suiiicient diameter to leave an annular space around the lower end of the mandrel 18. The bore 21 corresponds to two diametricallv Opposite, horizontal slots or openings 22 in the head 2, through which the strip of pasteboard, or the like, from `which the acking` disks or washers are out, is passed 1n the well-known manner.

The chute 12 communicates with a tube 23 secured to the outer wall of the casing 1, and the lower end of this tube extends sli ably into a corresponding tube 24.

The lower end of the piston 3 is forked, and between the forks there is disposed an axle-pin 26 which carries a roller 25. Below the latter there is disposed the horizontal insegne Q rod, the opening of the last-named cutter heend facing the other rod, to deect the cap ing smaller than said punch so that the latlaterally as it is carried along by the reter cannot pass through said cutter but will treating punch. force it toward said last-named rod, the 5. ln a machine for making and applying 5 first-named rod having an oblique surface at bottle caps, a reciprocating punch and means the end facing the other rod, to deect the coperating therewith for producing a bottle cap laterally as it is Carried along by the recap, a reciprocating capping die in longitutreating punch, a bottle cap applying mechdinal alinement with the said punch, means anism, and a chute for conveying the delocated between said'punch and said die and 10 iected caps to said mechanism. arranged to operate both of them, and means a. ln a machine for making bottle caps, a for conveying the caps from the cap-procasing, two longitudinally alining spaced ducing mechanism to said capping die.
